BUMPER FOZR- AUTOMOBILES.

Application filedMay 15, 1926. Serial No. 109,231.

My invention relates to bumpers "forautomobiles and other vehicles and .is exemplified inzan embodimentinmo'difiedform of the the-invention disd in my ,co-pending ap- Patent of the .United filed October ,6, 1925,

broad subject matter .of

plication for "Letters States -c0,710.

Serial Number The generalnobject of .my invention is to provide a novel construction of bumper for automobiles or. other like vehlcles 1n which the elements are combined.

in. a manner to produce a unitary structure. capable. ofaffording a maxlmum .OfiPIOtGCtlOIl 1n case of collision.

It. also-is ancobyect ofthe invention to provide a novelbutsimplified :bumper struc reeofa character such that it \may be manufactured at -a minimum .of. cost or expense.

To comprehends these and other ends the invention the broadaas well as ,thespecific features ofconstruction ashereinafter described in detail, particularly pointed out in the claimsandas depicted, in the drawing in which Ihave illustrated wconvenient embodiment In the drawing:

Fig. 1, isa view in topplan of the front chassis of a vehicle,

and of a bumper portionof the frame or such as an automobile,

mounted thereon, the said shown partly Fig. .2 is a view in front bumper, one end portion shown in vertical 7 section Fig. taken, on

one .form of a of the invention.

bumper being in horizontal section;

elevation of the thereof belng 3 -is a view in sectional. elevation the line of. Fig. 1;.and

1 Fig. 4: is -,a view in transverse .section taken on the line of'Fig. 2.

:Referring to the drawing :.The. front end portions ofthe oppositesides of the frame or chassis-of automobile. structure are shown at said end 1 portions 1 :are may be of any preferred or. other vehicle 1. Mounted upon'the. brackets 2 which form of construction and which may be secured to the end portions 1 of the opposite sides of the frame or chassis in any preferred known manner.

In the construction as shown the brackets 2 are each provided with slots or seats 3 within which the relatively narrow metal resilient spring plate member or bar 4: is

mounted. The said plate or in these slots or seats by The opposite end portions 0 bar 4: is secured means of bolts 5.

f the said metal 12 indicatedat 6, and constitute resilient spring members. These outwardly and forwardly if the bumper .is

plates or bars spectively, of

plate 4: beyond the outer sides of the bracket are inclined forwardly and outwardly, as

extending portions'fi are curved-as indicated, the convex sides with respect to the car structure. 'That is, located upon thefront end portions of the sidesof the frame 0r chassis the convex sides of the saidportions 6 face thereof facing outwardly...

forwardly, whereas if the bumper'shouldbe convex sides-would face rearwardly.

The outer ends of the'extenslons 6 ter- -minate in eyes 7 within which shackle "bolts 8 are mounted. These bolts are of substantially greater length than thewidth of the plate or bar 4 so that the opposite end ,portions.thereof project a substantial distance located upon the rear end of the car the said above and below the oppositeends of the I eyes 7 Relatively narrow metal spring 10 and ll'arealso provided and 13 at their opposite ends with. eyes 12 the upper andlower ends, re

which engage 10 and '11 in'theconstruction shown are straight but this is of the invention. These plates or barsvlO and 11 constitutetying means'for connectingthe outer ends of the extensions '6. The

the bo1ts'8. 'Theplatesor bars I not .an esesntial feature eyes 12 and 13 of the platesor bars 10 and 11 are retained upon the opposite end portions of the bolts 8 by means of nuts 15 and 16. The eyes 12 and 13 are spaced or separated. from the eyes 7 by means of spaclng washers 17. Thepresence of 'these washers 17 operates to space theopposite ends'of the said bars orplatesilO and 11. from the outer ends of the extensions 6 of the metal spring plate or bar 41. 'A metal spring plate 2OIis lconnected at its opposite ends by means of bolts 21 to intermediateportions of the extensions 6. The bolts 21 extend through openings 22 in thesaid ,ext'ensionsand a-lso through slots 23 in the opposite end portions forwardly in such manner that the outer rear sides thereof contact slidably with the front convex sides of the extensions 6.

The plates 10, l1 and 20 are connected to gether at their middle points by means of a vertical oval shaped bar 25. The said bar-125 is connected to each of the plates 10, 11 and 20 by means of bolts 26, 27 and 28.

In case of collision, if the impact shoulc be upon the portion of the bumper intermediate the opposite ends thereof, the tendency would be for the cross plates or bars 10, 11 and 20 to bend inwardly. Such tendency onthe part of the plates or-bars 10 and 11 would tend to cause inward movement of the opposite end portions 6. Such movement would be resisted to some extent by the curved spring bar 20. The opposite ends of the latter would slide against the inner front sides of the extensions 6, such sliding movement being permitted by the engagement of the bolts 21 with the slots 23.

By my invention I am enabled to provide a construction of bumper which possesses the requisite strength and ruggedness and which is extremely eflicient for the purpose for which such structures are intended.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In a bumper for vehicles, the combination of resilient spring members located at the opposite ends thereof, a cross-wise ex tending spring plate having slidable connection at its opposite ends with the said resillent spring members at polnts intermediate their ends, and tying means having connection at their outer ends with the said oppo-sitely disposed resilient spring members,

2. In a bumper for vehicles, the combination of resilient spring members located at the opposite ends thereof, a relatively narrow spring plate having slidable connection at its opposite ends with the said resilient spring members at points about midway between the inner and outer ends of said members, the middle portion of the said plate being curved outwardly and the opposite end portions thereof being curved inwardly and outwardly, relatively narrow spring plates having connection at their opposite ends with the outer ends of the said resilient spring members, one of the said plates being located above the said spring members and the other of said plates being located below the said spring members.

3. In a bumper for vehicles, the combination of resilient spring members located .at the opposite ends thereof, a relatively narrow spring plate mounted upon and extending between the said spring members, the middle portion of said plate being curved outwardly and the opposite end portions thereof being curved inwardly, the

outer ends thereof extending forwardly and outwardly and resting againstthe inner sides of the said spring members at points near the middles thereof, means for slidably connecting the opposite end portions of the said relatively narrow spring plate to the said spring members, relatively narrow spring plates connecting the outer ends of the said spring members, one of the said plates being located above and the other below "the said members, the middle portions of said last mentloned plates being in vertlcal'alinement with the first named relatlvely narrow curved plate, and means for connecting the middle portions of the said plates together.

4. In a bumper for vehicles, the combination of resilient spring members located at the opposite ends thereof, a relatively narrow spring plate mounted upon and extending between the said spring members, the middle portion of said plate being curved outwardly and the opposite end portions thereof being curved inwardly, the outer ends thereof extending forwardly and outdle portions of the saidplates together, and

a rigid bar'extending transversely of and connected to the said plates.

In testimony that I claim the foregoing asmy invention .1 have hereunto signed my name this 12th day of May," 1926.
